its 315: a big problem

"Yes." Yuefeng nodded, "I'm sorry, there is only this drink here, because I only like this one."

Xu Siyuan saw it as a star and drank it. She also tentatively picked up the cup and drank some, and then she couldn't help drinking all the cups. Obviously, she and Yuefeng have a lot in common. Yuefeng was happy about this and hurriedly poured another cup for her.

"In this way, are you also from a highly technologically developed planet?" The moon wind asked.

"Our place is called Earth, the solar system located in the Milky Way." Cheng Xing became excited and hurriedly reported to his home.

"Sorry, I don't know where it is." Moonlight shook his head regretfully, "You know, different civilizations call galaxies in the universe differently."

"This... is indeed..." Cheng Xingxing grinned, "So, you haven't been in contact with guests from the earth before?"

"No." Yuefeng shook his head and said, "They look the same as you, that is to say, we have come into contact with people who should belong to the same race, but they claim to be Yunsu people."

"When did that happen?" The star is excited again.

"Why, are you and Yunsu..." Yuefeng was a little surprised.

"Yes, I am both a native of the earth and a native of Yunsu." Cheng Xingxing smiled and said, "I crossed from the earth to Yunsu, and then came here from Yunsu for some reason."

"Is it because of the key of time and space?" The moon wind asked.

"You..." Cheng Xing was shocked, "How do you know this thing?"

"That's why I invite you to come here and talk alone." Yuefeng said with a smile, and then took a sip of the drink in the cup. As a star, it can be seen that he is a little excited.

"The key of time and space was originally stored on our Red Earth Star." The moon wind said amazingly, "That is the precious legacy left to us by our ancestors. Relying on its research, our scientific and technological research has made many breakthroughs."

"This is so surprising." Cheng Xingxing took a deep breath.

"What are you talking about?" Xu Siyuan couldn't help asking curiously. Cheng Xingxing patted her and said, "Don't be confused. I'm talking about the key things!" Xu Siyuan was so scared that she hurriedly shut up, for fear of annoying the kind underground man and not helping her go home.

"According to historical records, more than a thousand years ago, a Tibetan soldier from Yunsu mainland came to our world." Yuefeng said, "He has fully mastered the language of our red land, as if he had grown up in the red land since childhood. His arrival surprised us, not only because he knows our language, but more importantly, as soon as he appeared, the seven keys we put in the scientific research institute were missing. That's a red key, the same color as our red ground.

"So are the remaining six keys still there?" Cheng Xingxing stood up excitedly, "If so, can you lend it to me? I want to use them back to the earth. The earth is in crisis. I want to go back to save my parents!"

"Don't be excited." Yuefeng waved his hand gently. Cheng Xingxing realized that he had lost his temper. He sat down embarrassedly and said sincerely, "As long as I can go back to earth to save my parents, I will definitely find a way to send them back."

"They are no longer there." The moon breeze shook its head regretfully. The Tibetan army from Yunsu used his strong strength to help our tribe resist the attack of the ghost orcs at that time, and finally drove the orcs to the place of death. With his help, we can establish a genetic blockade belt, completely limit these ghost beasts to the land of death, and cannot step into the territory of our naked people.

"I went there. More than a thousand years ago, was it Qin Zheng?" Cheng Xing opened his mouth again.

"That's right!" This time it was the moon wind's turn to get excited, "Do you know him?"

"It's strange, why don't I remember such a past?" At this time, Cang Qu muttered to himself in the star's mind.

Huh? That's right! Cheng Mingxing was stunned: If that man is Qin Zheng, the soldiers he used to drive out ghosts and beasts must be Cangqu and Long Lao and others. Then... They should still remember the past. When they come to the red land, they should know where they have been?

"Do you recognize them?" Cheng Xingxing waved his hand anxiously, and several tiger charm doors opened at the same time. Long Lao, Mu Yun, and Jing Yan came out together.

"Sorry, are they?" Yuefeng's face apologized.

Cheng Xingxing patted himself on the head: I'm a pig! It happened more than a thousand years ago. At that time, there was no moonlight!

"His words are strange." Long Lao frowned and shook his head. "As the first soldier created by him, I can prove that Qin Zheng has never been to this place at all."

"What did you say?" Yuefeng looked at Long Lao and showed a surprised expression. You...are you created by Qin Zheng? But...but you're not..." He pointed to the star and didn't know what to say.

Xu Siyuan looked at Long Lao in a staring way and muttered in a low voice, "He is so convenient that even soldiers can speak naked words..."

"It's a long story." Cheng Xingxing sighed, "The general situation is like this."

He told Yuefeng everything without reservation. Chidi is a simple planet, and the creatures on it are so simple that they are called the kindest underground people. Whether there is a conspiracy or trick in their hearts, it can be seen that this kind of secret is meaningless to them. Besides, Cheng Xingxing finally met a intelligent creature with a high degree of civilization, which is called a common language. He just can't say more. He doesn't want to keep such a secret.

"It's wonderful." Moon wind sighed, "However, I think this may have something to do with the power of the key of time and space. Is it because the key of space-time disturbs space-time, resulting in many different plane worlds? Or, the universe is originally a multi-layer parallel space. The key of time and space breaks the limitations of space and brings another Qin Zheng, who is exactly the same as Qin Zheng in our universe, here?

"You say this..." Cheng Xingxing is a little big, but he, who loves to read science fiction movies and science fiction, is not so much that he can't understand the meaning. Instead, his brain is hot and he can't help thinking: "Is it possible that the Qin Zheng I met is not Yunsu's Qin Zheng, but... but another one. Another Qin Zheng on the plane?"

"What are you talking about?" Muyun's head is really big.

"Although I can't understand your words, I think it's really complicated." Cangqu said in the star's mind, "However, it seems that there is no need to delve into it. It doesn't make sense."

"Hmm." Cheng Xing couldn't help nodding. It really doesn't make sense. Whether Qin Zheng is the Qin Zheng of Yunsu or Qin Zheng of another world, he is dead, his era is over, and he has become a legend of a thousand years ago.

But Yuefeng obviously didn't think so. He became very excited and stood up and rubbed his hands: "This is a major new topic! This is a great new discovery! Mr. Cheng Mingxing, your appearance will change our view of time and space all the time. You must stay in the history of the scientific discoveries of the Red Earth people forever!"

"Don't, don't..." Cheng Xingxing waved his hand hurriedly, "I said that this kind of thing should not be thought by high school students like me. I just want to ask you, can you help me go back to Yunsu?"

"This is no problem!" Yuefeng shouted excitedly, but soon calmed down and said shyly, "I mean, I have no problem at all, but I don't know if the national leaders will allow it. But in my opinion, as long as you can agree to our conditions, the leaders will definitely help you realize all your wishes.

"I'll go! There are conditions again!" The star has a big head.

"Let's go back. I don't understand what you're talking about." Mr. Long gave him a foot impatiently, and his head was immediately not big. He hurriedly opened the door of the tiger charm and invited several people back.

"In the future, use your brain before you do it!" Mr. Long criticized him rudely, "Like this time, what a joke! Let's come out and admit that we are soldiers more than a thousand years ago, okay? Who can live so long!"

The star grinned with a big mouth, which was very embarrassing.

"Typ: Tell me about your conditions." Cheng Xingxing sighed, "You have found my weakness. I have to go back to Yunsu."

"It's not too complicated to help you return to the original world, but it costs a lot of money." When Yuefeng talked about money, he did not show the expression that Yunsu or those hypocrites on earth love money so much that they don't like to talk about money. Without the consent of the national leader, no one can send you back. We can't send you back to the earth, because you came here from Yunsu. We can only send you back to the space-time rift you used when you came through the ancient space-time gate. This also involves the topic that I haven't finished - the seven keys are gone, because Qin Zheng used our trust in him to steal all the seven keys after helping us clean up the ghosts and beasts.

"This is quite embarrassing." Cheng Xingxing grinned and then repeated it several times in his mind.

"Didn't you say in your complicated and difficult conversation just now that this Qin Zheng may not be the other Qin Zheng." Cang Qu replied to him casually.

"Let's talk about your conditions." Cheng Xingqi sighed.

"After the research of historians and scientists, we have reasoned out a possibility." Yuefeng did not say the conditions, but said something irrelevant: "Why can the Tibetan soldier Qin Zheng understand the language of Chidi so deeply? One of the most recognized speculations in thousands of years is that he brought one of the keys of time and space, that is, the red one, from another plane world. It is because of this key that he can master our language, and it is also because of the appearance of this key that the red key here will disappear. Because only one object can exist in the same time and space. The key held by Qin Zheng is closer to the 'origen" of the red key, so when it came to the red ground, the red key of the red ground disappeared.

"You made my head big again." Cheng Xingxing rubbed his head and said, "Well, I can understand things about different planes. I can also understand that there are many Qin Zheng. I have seen Dragon Ball and know that killing this Shalu, and the future world may not be saved... Forget it, you don't understand what you say... I don't understand what you said. Just say what you want me to do."

"You must also have a red key on you, right?" Yuefeng asked with a smile.

"What do you want to do?" The star star's eyes widened.
